2.Brian is heading out for a steady early morning jog as one of his training runs for a marathon. He plans to jog
18 miles. He covered the first 4 miles in 39 minutes. Keeping the same steady pace, which of the following
is closest to the time that it will take Brian to finish his jog from the 4-mile point?
(1) 2.3 hours
(3) 2.9 hours
(2) 2.5 hours
(4) 3.3 hours

Answers

It would be 2.9 hours because you would add 4 of the 39 minute intervals together and for the last interval if Brian ran extra 2 miles which would be 20 miles. You would have to divide the 39 minute interval by 2 since he ran an extra 2 miles to get 19.5 minutes for him to get his last 2 miles for his 18 mile jog. Then add the 4 intervals of 39 minutes along with the 19.5 minutes to get you a total of 175.5 minutes and if you were to convert that to hours and minutes it would be 2 hours and 55 1/2 minutes so technically it would be 2.9 hours. To find the 2.9 you would divided 175.5 by 60 since there is 60 minutes an hour to get the answer 2.925 unrounded, but rounded it would get you the final answer 2.9 hours.

Final answer: 2.9 hours.

Information related to Lisa Company's inventory at October 31 is given,

Suppose, find the value of ending inventory using the FIFO cost assumption if 500 units remains on hand at october 31

We need to calculate the value of ending inventory

Using FIFO method

[tex]value\ of\ ending\ inventory =305\ units\times\$10.6+195\ units\times\$11.60[/tex]

[tex]value\ of\ ending\ inventory = 3233+2262[/tex]

Step-by-step explanation:

Answer:

3,960 feet long

Step-by-step explanation:

1 mile = 5,280 feet

5,280 feet ÷ 4 (because the denominator is 4) = 1,320 feet

1,320 x 3 (the numerator is 3) = 3,960 feet

3/4 of a mile = 3,960 feet

ZWXY is a right angle, find each measure.
W
Х
z
Y
mZWXZ =
mZZXY =

Answers

Answer:

m∠WXZ = 38°

m∠ZXY = 52°

Step-by-step explanation:

In the question

∠WXZ and ∠ZXY are two adjacent angles and formed together ∠WXYThat means the measure of ∠WXY equal the sum of measures of ∠WXZ and ∠ZXY

∵ ∠WXY is a right angle

→ That means its measure is 90°

m∠WXY = 90°

m∠WXZ + m∠ZXY = m∠WXY

∵ m∠WXZ = (5x + 3)°

∵ m∠ZXY = (8x - 4)°

∵ m∠WXY = 90°

→ Substitute their values in the equation above

(5x + 3) + (8x - 4) = 90

→ Add the like terms in the left side

∵ (5x + 8x) + (3 - 4) = 90

∴ 13x + (-1) = 90

∴ 13x - 1 = 90

→ Add 1 to both sides

∴ 13x - 1 + 1 = 90 + 1

∴ 13x = 91

→ Divide both sides by 13

∴ [tex]\frac{13x}{13}=\frac{91}{13}[/tex]

x = 7

→ To find the measure of each angle substitute x by 7 in their measures

∵ m∠WXZ = 5x + 3

∴ m∠WXZ = 5(7) + 3

∴ m∠WXZ = 35 + 3

m∠WXZ = 38°

∵ m∠ZXY = 8x - 4

∴ m∠ZXY = 8(7) - 4

∴ m∠ZXY = 56 - 4

m∠ZXY = 52°

A. Width=9, Length=11
B. Width=6, Length=8
C. Width=4,Length=6
D. Width=3, Length=5

Answers

Answer:

width= 4, length= 6

Step-by-step explanation:

use perimeter formula and substitute values

so formula becomes:

20= 2(x+2) + 2(x)

expand the brackets and that gives us

20= 2x+4 +2x

so

16=4x

x= 4

so width is x which is 4

and length is x+2 which is 6


The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?

Answers

Answer:

The indifference point is 20 gallons.

Step-by-step explanation:

Giving the following information:

Quik-Clean Car Wash:

$15 for a car wash plus $2.50 per gallon for unleaded gasoline.

Mighty Clean Car Wash:

$10 for a carwash plus $2.75 per for unleaded gasoline.

First, we need to structure the total cost formula:

Quik-Clean= 15 + 2.5x

Mighty Clean= 10 + 2.75x

x= gallon of gasoline

Now, we equal both formulas and isolate x:

15 + 2.5x = 10 + 2.75x

5 = 0.25x

20 = x

The indifference point is 20 gallons.

Prove:

Quik-Clean= 15 + 2.5*20= $65

Mighty Clean= 10 + 2.75*20= $65

Which is the equation of the graphed line written in
standard form?
A. Y=c
B. X-1/2y=0
C. X-y=0
D. Y= 1/2x

Answers

Answer:

C. x - y = 0

Step-by-step explanation:

Step 1: find the slope (m) and y-intercept (b) of the graphed line.

Using the two points on the line (0, 0) and (2, 2),

Slope = [tex] \frac{rise}{run} = \frac{2 - 0}{2 - 0} = \frac{2}{2} = 1 [/tex]

The y-intercept (b) is the point at which the line intercepts the y-axis. Therefore, the y-intercept (b) = 0

Step 2: Generate an equation for the line in slope-intercept form using b = 0 and m = 1.

Substitute m = 1 and b = 0 into y = mx + b

y = 1(x) + 0

y = x

Step 3: rewrite the equation from slope-intercept form to standard form.

To express I'm standard form, take all terms with coefficient to the left, and leave the constant on the right side of the equation.

y = x

Subtract y from both sides

y - y = x - y

0 = x - y

x - y = 0

Which graph shows h(x) = (f(x))(g(x))?

Answers

Hi! I'd be happy to help you. However, there is not enough information here for us to help, as there is no way to tell which graph is correct without the equations of f(x) and g(x). They'd look something like:

"f(x) = x-2," or "g(x) = 7x+3."

Are you able to provide the equations of of f(x) and g(x)? I would be more than happy to help.

----------------------------------------------------------------------------------------------------------------

UPDATE: I did not realize that you could solve this problem without the original equations. Please refer to the other user's response for an amazing and detailed explanation of this problem! :)

Answer:

The first graph.

Step-by-step explanation:

We want to find the graph that shows:

[tex]h(x)=f(x)g(x)[/tex]

Notice that g(x) is a line and f(x) is a quadratic.

So, their product must be a cubic.

Also, g(x) and f(x) is the same across all four graphs. The only difference is h(x).

Notice that our quadratic f(x) is curving upwards. Therefore, the leading coefficient of f(x) is positive.

Notice that the line g(x) is sloping downwards. Therefore, the leading coefficient of g(x) is negative.

So, this means that the leading coefficient of our cubic h(x) must be negative since a positive times a negative yields a negative.

Remember that the parent cubic function has a positive leading coefficient and it rises from left to right.

So, if our leading coefficient is negative, the cubic will fall from left to right.

Therefore, we can eliminate the 2nd and 3rd graphs since in those two, h(x) has a positive leading coefficient.

Now, we can just pick a test point and determine whether our graph is the first or the fourth.

Let's let x = -2. So, we have the equation:

[tex]h(x)=f(x)g(x)[/tex]

Substitute all Xs for -2s:

[tex]h(-2)=f(-2)g(-2)[/tex]

Looking at the graphs, we can see that f(-2) is 8. g(-2) is 0.5. Substituting this back, we get:

[tex]h(-2)=8(.5)=4[/tex]

So, h(-2) should be 4.

For the first graph, h(-2) is indeed 4.

For the second graph, h(-2) is 6.

So, the correct graph that represents f(x)g(x) is the first graph.

And we're done!
